CEROGRAPHIC PEN IL.

To all whom it may concern:

Be it known that we, ALBERT REIMANN and LEO SCHNEIDER, citizens of the Empire of Germany, residing at Berlin, in the Em-' pire of Germany, have invented a new and useful Cerographic' Pencil, of which the following is a specification.

. ing or dyeing process or both processes.

The cerographic pencil is adapted for adjusting and arbitrarily regulating the discharge of the mass introduced into it and for automatically stopping the discharge at any moment. The mass may be charged into the pencil either in a liquid or in a solid state, in which latter case means are proshows in elevation a modification of the upvided for warming and liquefying the mass.

We will now proceed to describe our invention with reference to the accompanying drawings, in which Figure 1 is a vertical longitudinal section through one form of the invention, Fig. 2 is an elevation of the same, the lower part being modified and shown in section, Fig. 8

per part of the pencil, Fig. 4 is a detailed view of a portion .of the device, and Fig. 5 is a horizontal section through "the line A-B in Fig. 4:.

Similar letters of reference refer to similar parts throughout the several views.

The cerographic pencil shown at Fig, 1

consists of a metallic tube a, a mouthpiece g and a handle d. The handle (2 made from handle from inadvertent movement.

a bad heat conductonis' preferably made shiftable on the tube a for the purpose here inafter set forth and the latter is provided 'With a bent leaf spring a for preventing the tubular piece m isin any known manner fastened in the lower widened end of the tube a and is closed with a disk I; having a central bore and a few lateral holes b. The end of the piece m projecting from the tube a is externally screw-threaded and on this end engages the internal thread of the mouthp ece g. The central'cavity of the latterisshown glass, stone, etc., by v A shortv Specification of Letters Patent. Patented Mar. 21 1911. Application filed October 3, 1908. Serial No. 455,970.

. as partly conical and partly cylindrical in two steps. The shoulder f formed between these two steps serves as a seat for a diskvalve k which is made in one piece with a bolt and is smaller in diameter than the larger step. The bolt 11 is guided in the smaller step of the said cavity below and in the central bore of the disk I) v.aloove and is longitudinally cut away on one side over its art beneath the disk-valve 72., so as to form 1n its guidean outlet for the liquid mass flowing out ofthe tube a and the mouthpiece g! Normally the disk-valve h is pressed on its seat f by a helical spring is bearing on it and on the disk 6. The bolt i normally projects a little from the mouthpiece g and-it will be understood, that by pressing the pencil with its bolt 6 by means of the handled on the fabric, leather, paper, wood, etc., the bolt '5 will be pushed inward to open the diskvalve h and to permit the discharge of the liquid mass. The more the pencil is depressed, the more liquid will flow out of'it.

.The wax, stearin, tallow, etc., is introduced.

into the tube a through its upper mouth. When this mass requires to be liquefied, the mouthpiece g or the tube a will have to be placed. in the flame of some spirit-lamp or other heating apparatus for warming the mass. The heating of the tube a may be accomplished after the handle d has been either removed or pushed toward the upper end of the pencil to expose-a sufficient portion of the metallic tube a to be acted upon by the heating medium. The upper end of the tube a may be closed with an elastic cover 6 of any known construction for preventing the liquid "in the tube a: from flowing over, should the pencil be inclined during use.

where so preferred, the helical spring is maybe replaced by a weight, the disk-valve being made larger and heavier, such as Z in Fig. 2,, so that it is pressed by its own weight on its seat.

The upper end of the tube a may be made like a funnel, see Fig. 3, forincreasing the capacity of the tube, in which case the hantube a from below.

Where so preferred, the pencil may be provided with means for heating itself the mass. F or example a clamp g (Figs. 4 and dle 0? may be arranged to be put over the i 5) .may be fastened on the mouthpiece g and be provided-with platinum-black, which has 5 the known property of becoming glowing on encountering a current of air or on being blown at. i

We claim:

1.' A cerograph pencil comprising a tube adapted to contain-wax, a combined means for controlling the flow of wax from the tube, and for applying the wax to the surface receiving the same, and means surrounding the lower end of the pencil for heating the material in the tube,

2. A cerograph pencil comprising a tube, having a widened end, a tubular piece secured in said end, said tubular piece having screw threads thereon, a mouth piece screwed to said tubular piece, ahandle surrounding said tube and a portion of the mouth piece, a perforated block in the tubular piece, a bolt projecting into the mouth piece and having its rear end passing through one of the perforations in the block, a collar on the bolt, a spring surrounding the bolt and bear ing against the collar and tending to keep the collar in position to close the mouth piece, said bolt having its ends projecting through the mouth piece.

3. A cerograph pencil comprising a metallic tube adapted to contain a heated material, means at its lower end for controlling the flow of-material and for applying it to the surface to be written upon, and a lon tudinally movable handle surroundin tie tube, said handlebeing composed 0 non heat-conducting material.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
